The Bayer designation ψ Aquarii (psi Aquarii, ψ Aqr) is shared by three stars/star systems in the constellation Aquarius:
- ψ1 Aquarii (91 Aquarii), a multiple star system with an exoplanet orbiting the giant primary
- ψ2 Aquarii (93 Aquarii), a solitary Be star

All of them were members of the asterism 羽林軍 (Yǔ Lín Jūn), Palace Guard, in the Encampment mansion.[1]
